30  Basics
Charging the battery
The battery is partially charged when shipped. Before you turn on 
and start using your phone, it is recommended that you charge 
the battery. Some batteries perform best after several full charge/
discharge cycles.
Only the power adapter and USB sync cable provided with your 
phone must be used to charge the battery.
Do not remove the battery from the phone while you are charging it 
using the power or car adapter.
1. Plug the power adapter into the USB connector of your phone.
2. Plug in the power adapter to an electrical outlet to start charging 
the battery.
As the battery is being charged, the notification LED shows a solid red 
light. The light turns to solid green when the phone is fully charged.
